Abstract

The ANTARES neutrino telescope has an energy threshold of a few tens of
GeV. This allows to study the phenomenon of atmospheric muon neutrino disappearance due to neutrino oscillations. In a similar way, constraints on the 3+1 neutrino model, which foresees the existence of one sterile neutrino, can be inferred. Using data collected by the ANTARES neutrino telescope from 2007 to 2016, a new measurement of ¿m2 32 and ¿23 has been performed — which is consistent with world best-fit values — and constraints on the
3+1 neutrino model have been derived.
